Summary: %c in ARM inline asm leads to ICE (in
arm_print_operand)
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: inline-asm
AssignedTo: unassig...@gcc.gnu.org

minimized test case
Compiling the attached file leads to ICE with a GCC 4.6.0 ARM cross-compiler.
It uses inline asm with %c and an element of a structure. If the referenced
"state" element is made the first element of the structure, the file compiles
successfully.
